In 2005 both appeared on the reality show "The Surreal Life," where Knight met his bride, "America's Top Model" winner Adrianne Curry.
Apparently, Henderson didn't approve.
Last week Henderson told reporters the two were pushed into getting engaged by VH1, saying, "they asked if I could come and counsel them before the marriage and I said 'no, but maybe I'll come and counsel the divorce.'"
"They were very, very upset that Florence made these comments," InTouch Weekly Senior Editor Kim Serafin told Early Show National Correspondent Hattie Kaufmann.
In the reality show "My Fair Brady," the couple played out their marriage woes before the camera.
Knight stands by his marriage, saying he loves Adrianne with all his heart and that Henderson's remarks hurt him deeply. "I was nothing but nice to her when we met and she had it out for me," Curry said.
There's been Brady gossip before. Barry Williams, who played the oldest son, Greg, claimed he dated his onscreen mom. Maureen McCormick, who played the oldest daughter, Marcia, is writing a tell-all book describing bulimia and depression on set.
"I think we care about them because we all grew up with them," said Serafin. "Now we see through their blogs, that maybe they weren't always the perfect family we thought they were."
